Environment-friendly long-acting transparent BOPP (Biaxially-oriented Polypropylene) master batch with high wetting tension

The invention belongs to a plastic film material, and particularly relates to an environment-friendly long-acting transparent BOPP (Biaxially-oriented Polypropylene) master batch with high wetting tension for a transparent BOPP film. The master batch is prepared from the following components: 60-80% of polypropylene resin, 1-10% of organic modified nano montmorillonite, 3-10% of polypropylene grafted hydroxyethyl methylacrylate, 2-10% of polyamide-6, 5-15% of ethylene-vinyl alcohol copolymer, 5-20% of polyethylene methacrylic acid copolymer and 0.2-1% of a heat stabilizer. The problem of solvent residue is solved, the polypropylene refining structure is improved by utilizing the organic modified nano montmorillonite, and the organic modified nano montmorillonite is used as a blocking agent to reduce the binding capacity of polypropylene and a solvent. 本发明属于塑料薄膜材料，具体涉及一种用于透明BOPP薄膜的环保长效高润湿张力透明BOPP母料，由如下成分组成：聚丙烯树脂60-80％、有机改性纳米蒙脱土1-10％、聚丙烯接枝甲基丙烯酸羟乙酯3-10％、聚酰胺-6 2-10％、乙烯-乙烯醇共聚物5-15％、聚乙烯甲基丙烯酸共聚物5-20％、热稳定剂0.2-1％。本发明解
